Java编程过程中,Integer对象(或其它继承自Number类的包装类对象)使用Number包装类内置的compareTo()方法来比较调用对象和参数之间的大小的时候,Java的集成开发环境IDE或编译器给出了提示:The method compareTo(Integer) in the type Integer is not applicable for the arguments (Float),后类似的提示,这是怎么回事呢?
int[] b = new int[10000]; int n = in.nextInt(); for(int i=1; i<=n; i++){ a[i] = in.nextInt(); } for(int i=1 ;i<=n; i++){ b[i] = in.nextInt(); } }//将输入带到function()方法里去运算 System.out.println(function(a,b)) } 3. 每行测试数据的数量在该行开...
